Nuclear export of BATF2 enhances colorectal cancer proliferation through binding to CRM1

Clinical and Translational Medicine, 2023
Background During the tumourigenesis and development of colorectal cancer (CRC), the inactivation of tumour suppressor genes is closely involved, although detailed molecular mechanisms remain elusive.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Repression of classical nuclear export by S-nitrosylation of CRM1 [PDF]

Journal of Cell Science, 2009
The karyopherin chromosomal region maintenance 1 (CRM1) is the major receptor for classical nuclear protein export. However, little is known about the regulation of CRM1 itself. Here, we report that cellular CRM1 became S-nitrosylated after extensive exposure to endogenous or exogenous nitric oxide (NO).

Insights into the function of the CRM1 cofactor RanBP3 from the structure of its Ran-binding domain.

PLoS ONE, 2011
Proteins bearing a leucine-rich nuclear export signal (NES) are exported from the nucleus by the transport factor CRM1, which forms a cooperative ternary complex with the NES-bearing cargo and with the small GTPase Ran.

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

NESdb: a database of NES-containing CRM1 cargoes

Molecular Biology of the Cell, 2012
The leucine-rich nuclear export signal (NES) is the only known class of targeting signal that directs macromolecules out of the cell nucleus. NESs are short stretches of 8–15 amino acids with regularly spaced hydrophobic residues that bind the export karyopherin CRM1. NES-containing proteins are involved in numerous cellular and disease processes.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

The Interaction of CRM1 and the Nuclear Pore Protein Tpr

PLoS ONE, 2014
While much has been devoted to the study of transport mechanisms through the nuclear pore complex (NPC), the specifics of interactions and binding between export transport receptors and the NPC periphery have remained elusive. Recent work has demonstrated a binding interaction between the exportin CRM1 and the unstructured carboxylic tail of Tpr, on ...

Give me a SINE: how Selective Inhibitors of Nuclear Export modulate autophagy and aging

Molecular & Cellular Oncology, 2018
Autophagy is a cellular recycling process leading to lysosomal degradation of damaged macromolecules, which can protect cells against aging. The transcription factor EB (TFEB), a major transcriptional regulator of genes involved in autophagy and ...

R‐Loops Mediated Odontogenic Differentiation of hDPSCs by Activating the cGAS‐STING Pathway Under Inflammatory Microenvironment

Oral Diseases, EarlyView.
ABSTRACT Background R‐Loops are three‐stranded DNA/RNA hybrids implicated in immune responses. Their role in mesenchymal stem cell differentiation, particularly in dental pulp regeneration under inflammation, remains unclear. Methods Rat pulpo‐dentinal complex (PDC) injury models and LPS‐stimulated human dental pulp stem cells (hDPSCs) were used.
